You either have not read the article, or have no concept of pharmacology (or, possibly, both).
The quantity of 240mg per day is meaningless. What we are interested in is: 240mg *of what*? Try taking a daily dose of 240mg of Foxglove extract; or Ergot infected wheat. I think you'll find quite a profound effect!
This particular study used "Ginko Biloba Extract". All well and good - but what, precisely, was extracted (and what was, therefore, thrown away)? From the manufacturers website:
One ton (1,000 kg) of the dried leaves yields only 20 kg of EGb 761® Ref.
contains approximately 24% flavone glycosides (primarily quercetin, kaempferol and isorhamnetin) and 6% terpene lactones (2.8-3.4% ginkgolides A, B and C, and 2.6-3.2% bilobalide). Ginkgolide B and bilobalide account for about 0.8% and 3% of the total extract, respectively. Ref.
Therefore, by my maths, this study used an extract equivalent to 12 gram of dried leaf per day; a pretty reasonable dose - certainly considering that the same company sells 40mg capsules of EGb 761®. More importantly, patients received a *standardised* extract; We're not talking about Holland & Barrett bargain cheapo tea-leaves here!
It's a rather interesting article. Rather less surprisingly, the manufacturer of the product used in the study has not updated their "latest News" section to include these results!
